The compounds that act as safeners or antidotes are herbicidally active compounds that may be included in the herbicidal composition of the present invention, and these compounds neutralize the damaging effect of compounds on the crop plants virtually completely without adversely affecting the herbicidal activity against weeds. At least one of said safeners or antidotes may be used in a mixture with the herbicidal composition of the present invention.

As used herein, the term “dry-field farming” refers to cultivating field crops, including, but not limited to, potatoes, sweet potatoes, carrots, Chinese cabbages, radishes, com, watermelons, lettuce, sesame or perilla leaves, beans, Perilla japonica, sesame, red pepper, cucumbers, eggplants, and kale. As used herein, the term “paddy field farming” means farming that is performed by water irrigation, and typical examples thereof include rice farming. As used herein, the term “nonselective herbicide” refers to one that Mils all plants without distinction between crops and weeds. Specifically, “non-selective herbicide” refers to one that can kill all plants which grow not only in rice fields and gardens, but also places in which crops are not cultivated, including fallow areas, the bank around a rice field, and a furrow.

The herbicidal composition of the present invention can be used in a mixture with other known herbicides or a formulation thereof. The active compounds in the herbicidal composition of the present invention are applied in the form of ready mixes. However, the active compounds can also be formulated individually and mixed upon use, i.e., applied in the form of tank mixes. The composition of the present invention may be mixed with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellents, growth substances, plant nutrients and agents which improve soil structure. For particular application purposes, in particular when applied post-emergence, it may furthermore be advantageous to incorporate, in the formulations, mineral or vegetable oils which are tolerated by plants (for example the commercial product “Rako Binol”) or ammonium salts, for example, ammonium sulfate or ammonium thiocyanate, as further additives.

The herbicidal composition of the present invention can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. It is used in the customary manner, for example by watering, spraying, atomizing, dusting or broadcasting.

The herbicidal composition of the present invention may include one or more compounds represented by formula 1 as active ingredients. Moreover, the uracil compound may be a free base of the compound represented by formula 1 or an agrochemically acceptable salt thereof. In addition, because one or more chiral carbons can exist in the molecular structure of the compound represented by formula 1, the definition of the uracil compound of the present invention includes single enantiomers, diasteromers, racemates and the like.

Examples of an agrochemically acceptable salt of the compound represented by formula 1 include metal salts, salts with organic bases, salts with organic acids, salts with organic acids, salts with basic or acidic amino acids, and the like. Metal salts include, for example, alkali metal salts, such as sodium or potassium salts, alkaline earth metal salts, such as magnesium or barium salts, aluminum salts, and the like. Salts with organic bases include, for example, salts with trimethylamine, triethylamine, pyridine, picoline, 2,6-lutidine, ethanolamine, diethanolamine, triethanolamine, cyclohexylamine, dicyclohexylamine, N,N-dibenzylethylenediamine and the like. Examples of salts with inorganic acids include salts with hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid, phosphoric acid, etc. Examples of salts with organic acids include salts with formic acid, acetic acid, trifluoroacetic acid, phthalic acid, furmaric acid, oxalic acid, tartaric acid, maleic acid, citric acid, succinic acid, methanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, etc. Examples of salts with basic amino acids include salts with arginine, lysine, ornithine, etc. Examples of salts with acidic amino acids include salts with aspartic acid, glutamic acid, etc.

According to the invention, it is possible to treat all plants and parts of plants with the herbicidal composition of the present invention. The term plants should be understood here to mean all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant vareties which can or cannot be protected by varietal property rights. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoots, leaves, flowers and roots, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes. Parts of plants also include vegetative and generative propagation material, for example seedlings, tubers, rhizomes, cuttings and seeds.

The treatment of plants and parts of plants with the herbicidal composition of the present invention is carried out direcdy or by action on their environment, habitat or storage area according to customary treatment methods, for example by dipping, spraying, evaporating, atomizing, broadcasting, brushing-on and, in the case of propagation material, in particular in the case of seeds, furthermore by one- or multi-layer coating. Among the plants obtained by biotechnological or genetic engineering methods or by combinations of these methods, emphasis is given to those plants which tolerate the so-called 4HPPD, EPSP and/or PPO inhibitors, such as, for example, Acuron plants.

The herbicidal composition according to the invention can be applied to the following plants. However, the use of the active compound combinations according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants:

Dicotyledonous weeds: Abutilon, Amaranthus, Ambrosia, Anoda, Anthemis, Aphanes, Atriplex, Bellis, Bidens, Capsella, Carduus, Cassia, Centaurea, Chenopodium, Cirsium, Convolvulus, Datura, Desmodium, Emex, Erysimum, Euphorbia, Galeopsis, Galinsoga, Galium, Hibiscus, Ipomoea, Kochia, Lamium, Lepidium, Undernia, Matricaria, Mentha, Mercurialis, Mullugo, Myosotis, Papaver, Pharbitis, Plantago, Polygonum, Portulaca, Ranunculus, Raphanus, Rorippa, Rotala, Rumex, Salsola, Senecio, Sesbania, Sida, Sinapis, Solanum, Sonchus, Sphenoclea, Stellaria, Taraxacum, Thlaspi, Trifolium, Urtica, Veronica, Viola, and Xanthium;

Dicotyledonous crops: Arachis, Beta, Brassica, Cucumis, Cucurbita, Helianthus, Daucus, Glycine, Gossypium, Ipomoea, Lactuca, Linum, Lycopersicon, Nicotiana, Phaseolus, Pisum, Solanum and Vicia;

Monocdtyledonous weeds: Aegilops, Agropyron, Agrostis, Alopecurus, Apera, Avena, Brachiaria, Bromus, Cenchrus, Commelina, Cynodon, Cyperus, Dactyloctenium, Digitaria, Echinochloa, Eleocharis, Eleusine, Eragrostis, Eriochloa, Festuca, Fimbristylis, Heteranthera, Imperata, Ischaemum, Leptochloa, Lolium, Monochoria, Panicum, Paspalum, Phalaris, Phleum, Poa, Rottboellia, Sagittaria, Scirpus, Setaria, and Sorghum;

Monocotyledonous crops: Allium, Ananas, Asparagus, Avena, Hordeum, Oryza, Panicum, Saccharum, Secale, Sorghum, Triticale, Triticum, and Zea.

The herbicidal compositions according to the invention can be used both in conventional methods of cultivation (strip cultivation with suitable strip width) and in plantation cultivation (e.g., vines, fruit, citrus), as well as in industrial plants and track systems, on roads and squares, but also to handle stubble and in the minimum-tillage method. They are also suitable as burners (for killing foliage, e.g. in potatoes) or as defoliants (e.g. in cotton).

They are also suitable for use on fallow areas. Other areas of use are in tree nurseries, forests, grasslands, and in the cultivation of ornamental plants. The herbicidal composition according to the invention can be converted into the customary foundations, such as solutions, emulsions, wcttable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

The herbicidal composition according to the invention can be applied before and after the plants have emerged, that is to say pre-emergence and post-emergence. It can also be incorporated into the soil before sowing. The good herbicidal activity of the herbicidal composition of the present invention can be seen from the examples which follow. While the individual active compounds show weak points regarding the herbicidal activity, the combinations, without exception, display a very good activity against weeds, which exceeds a simple additive effect. A synergistic effect in herbicides is always present when the herbicidal activity of the active combination exceeds the activity of the active compounds when applied individually.

The expected activity for a given combination of two herbicides can be calculated as shown in the following equation 1 (COLBY, S. R., “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, pages 20-22, 1967):

E=X+Y−(X×Y/100)  Equation 1

In Equation 1,

X is % damage by uracil compound (a) of formula 1 at the rate of application of p kg/ha; Y is % damage by conventional herbicidal compound (b) at the rate of application of q kg/ha; and E is the expected damage caused by compounds (a) and (b) at a rate of application of p and q kg/ha.

To test herbicidal activities, (1) in the case of non-selective herbicidal compositions, weeds at the growth stage (30-40 cm) in fallow areas and orchards were treated with compositions containing the uracil compounds and herbicidally active compounds. (2) In the case of dry-field farming, weeds at the initial growth state (5 cm or less) in wheat and com fields weeds were treated with compositions containing the uracil compounds and herbicidally active compounds. (3) In the case of paddy field farming, weeds in rice fields were treated with compositions containing the uracil compounds and herbicidally active compounds at 15 days after rice transplantation.

Herbicidal activities were visually evaluated by comparing the mortality of the plants with untreated control groups 20 days after treatment with the compositions.

Meanwhile, if the actual damage exceeds the calculated value, then the activity of the combination is superadditive. The expected activity for a given combination of two herbicides can be calculated using equation 1 above.

Example 1: Nonselective Herbicidal Composition

Weeds at the weed growth stage (30-40 cm) in fallow areas and orchards were treated with nonselective herbicidal compositions containing the uracil compounds and herbicidally active compounds.

Experimental Example

Tables 2 to 29 below show the plant mortalities (herbicidal activities) obtained when Echinochloa crus, Digitaria sanguinalis, Abutilon theophrasti, Aeschynomene indica and Xanthium spinosum were treated with the indicated amounts of uracil compounds, nonselective herbicides, and uracil compound/herbicide mixtures. When the measured values are higher than the calculated values, the test materials have significant herbicidal activities. The left column of two columns for each grass in the following tables indicates measured mortality values, and the right column indicates calculated mortality values.

In addition, the mixture of the uracil compound and the conventional dry-field farming herbicide did not show herbicidal activity for wheat and corn, suggesting that it can be used as a herbicidal composition for dry-field farming.

Example 3: Herbicidal Composition for Paddy Field Farming

In the case of herbicidal compositions, weeds in rice fields were treated with compositions comprising the above uracil composition and herbicidally active compound at 25 days after rice transplantation.

Comparative Example

The procedure related to Table 53 below was carried out in the same manner as the procedure related to Table 52, except that Carfentrazone was used in place of the uracil compound.

Table 53 below is for comparison with Table 52 and shows that a 2.5:10 mixture and 5:5 mixture of compound 36 and Pyrazosulfuron showed the highest herbicidal effect. The left column of two columns for each grass in the following table indicates measured mortality values, and the right column indicates calculated mortality values.

As can be seen in Tables 51 to 53 above, the mixture of the uracil compound and the conventional paddy field farming herbicide showed a higher herbicidal activity than that of each compound and also showed a higher herbicidal activity of the mixture comprising carfentrazone in place of the uracil compound. In addition, the mixture of the uracil compound and the conventional paddy field farming herbicide did not show herbicidal activity for the rice plant, suggesting that it can be used as a herbicidal composition for paddy field farming.

As described above, the herbicidal composition according to the present invention comprises, as active ingredients, the uracil compound represented by formula 1 and a herbicidally active compound, and thus exhibits excellent herbicidal activity while having a very high compatibility with crops. In addition, the herbicidal composition of the present invention shows excellent effects not only on selective control of monocotyledonous and dicotyledonous weeds in various crops, for example, wheat, barley, oat and corn, but also on control of monotxityledonous and dicotyledonous weeds in semi- and non-selective areas.

As can be seen from the results of the above examples carried out by the present inventors, the inventive herbicidal composition comprising both the uracil compound and the herbicidally active compound showed excellent herbicidal activity thanks to the synergistic action of these active ingredients compared to the herbicidal composition comprising the uracil compound or the herbicidally active compound individually. This increased herbicidal activity is a remarkable effect which could not be predicted by those skilled in the art.

In addition, the herbicidal composition of the present invention could be tolerated by a variety of crops and could effectively control even weeds which are usually difficult to control. Thus, the herbicidal composition of the present invention is a broad-spectrum herbicidal composition.

Accordingly, the herbicidal composition of the present invention has excellent herbicidal activity against weeds, can selectively control monocotyledonous and dicotyledonous weeds in useful crops and can also control monocotyledonous and dicotyledonous weeds in semi-selective and non-selective areas.
